When a website, or any appliance, for that matter, becomes a verb, you know they have done something right. "To digg" has become an important addition to this noun-turned-verb crowd. Do you think it annoys Yahoo! that despite their best efforts, their name as a verb means something like "to make a fool of oneself?"

• You can submit your own content to Digg; however, whether your content is dugg en masse has a lot to do with the status of the person who submits the article. Think of it as Washington DC. You want to get an influential lobbyist to work on your behalf, because even if your initiative is awesome, no one will listen if you have no reputation.
• When someone else diggs your content without your knowledge, you'll probably not be ready for a huge increase in traffic. If your site is strong enough, an untimely digg isn't going to hurt you. In fact, as Guillaume Bouchard mentions in his blog post about being dugg during alpha phase, the traffic served as a free stress test, and the Digg comments were a free usability report.
• If you have digg-worthy content, consider enabling a comments form, or some type of participation, whereby users have to register in order to participate. This way, your Digg referrals should result in more people registering and being more inclined to become regular visitors.
• You cannot have everyone in your office digg what you've submitted. The site's editors will notice that a lot of diggs are coming from the same IP address, and their most likely course of action will be to ban you and your workmates' accounts. Trust me. Of course, having a bunch of different usernames will achieve the same result.
• If you're dugg and your servers can stand the load, the traffic you gain from such an occurrance is priceless.
